The BIAN Service Landscape is a reference structure that categorizes and organizes BIAN Service Domains for ease of access. Different criteria can be used to classify and organize Service Domains that would result in different layouts of the standard set of BIAN Service Domains. BIAN uses a ‘primary’ Service Landscape view based on agreed categorizations that have been refined in use by the BIAN membership.
The BIAN Metamodel is a detailed and comprehensive (UML) model that defines all the BIAN design structures – it is fully documented elsewhere in its own guide (The BIAN Metamodel). The Metamodel has three elements that capture the design of the BIAN Service Landscape.
- Business Area – is the highest-level classification. A business area groups together a broad set of business capacities. For the BIAN Service Landscape they are defined to be aspects of business activity that have similar supporting application and information-specific needs.
- Business Domain – at the next level, business domains define a coherent collection of capacities within the broader business area. In the BIAN Service Landscape the business domains are associated with skills and knowledge recognizable in the banking business.
- Service Domain – is the finest level of partitioning, each defining unique and discrete business capacities. The Service Domains are the ‘elemental building blocks’ of a service landscape.
The Service Domain relates to generic capacities that do not vary in their scope, but the definitions of the Business Domain and Business Area are classifications that are specific to a particular Service Landscape layout. The Service Landscape layout can be varied depending on use.

+ 2000 Business scenarios
+ 2500 Service definitions
+ 170+ Semantic API’s available in BIAN’s API portal
New API Developers Guide
New release of:
– Business Capability Model

Additional Pilots of the Coreless Bank
- Substantial updates to the BIAN Metamodel and content
- Significant change in the definition and mapping of Action Terms to the Service Domain Functional Patterns, to improve the mapping to REST

- BIAN “How-to Guide II” – Design Principles & Techniques
- BIAN “How-to Guide III” – Developing Content
- BIAN “How-to Guide IV” – Applying the BIAN Standard
The “How-to Guide” gives organisations a toolset for using and implementing the BIAN model in their own organisations.
SL 3.0 – April 2014
Total of 280 Business Capacities (called Service Domains) 180 business scenarios added
The “How To Guide” has turned the 3.0 release into a comprehensive set of documents for different targeted groups:
